Carpet Bombing in Cyber Space - Say Again?

I was pointed to an article in the Armed Forces Journal where Col Charles W. Williamson III argues that the US Air Force needs to develop a BOTnet army as part of the US military capability for retaliatory strikes.

New Threats Demand a New Approach to DDoS Protection

In the past 24 months, distributed denial of service (DDoS) attacks have changed profoundly. Gone are the days when attackers worked under the radar, when machines were infected by botnet code unknowingly and attacks were disguised leaving very little to trace the exact origin. ...
